The Impact of a Jet apparatus consists of a cylindrical clear acrylic fabrication with provision for levelling. The dead weight of the moving parts is counter-balanced by a compression spring. The vertical force exerted on the target plate is measured by adding the weights supplied to the weight pan until the mark on the weight pan corresponds with the level gauge. A weight carrier is mounted on the upper end of the stem. A total of four targets are provided: a flat plate, a 120 cone and a hemispherical cup. Water is fed through a nozzle and discharged vertically to strike a target carried on a stem which extends through the cover.

Pressure and Vacuum gauges are connected on delivery and suction side of pump for the purpose of measurement. The flow rate of water is measured using measuring tank and Digital Timer provided in our Impact of Jet Apparatus. Impact of Jet Apparatus consists of a centrifugal pump coupled with electrical motor, supply tank, measuring tank & pipe fittings for closed loop water circulation.

Experiments :
To investigate the forces produced by a water jet striking a flat or a curved surface.
The apparatus is supported on a PVC base into which a vertical water supply pipe is fitted. Surrounding the supply pipe is a transparent plastic shield fitted with a top PVC flanged cover assembly. Impact of Jets apparatus enables experiments to be carried out on the reaction of a jet of water on vanes of various forms. In operation, water from the Hydraulics Bench is fed into the unit and a vertical jet is produced through the supply pipe and its interchangeable nozzle. The water from the jet is deflected by the reaction vane under test, and drains away through the large aperture in the base of the chamber. The reaction vane is held within the transparent shield approximately 20 mm above the vertical water supply pipe nozzle by a rod which passes through the top cover and supports a flat tray, onto which masses may be placed. Three different types of reaction vane are supplied with the apparatus and the types are flat, hemispherical cup and 45° cone form. The force produced by the jet impinging on the target is transmitted by the rod, to the flat tray where weights are placed in order to balance this transmitted force. Two interchangeable nozzles for the supply pipe are supplied, one of 8 mm and one of 5 mm diameter. Each vane can be secured to the pivot arm by a set screw and when not in use is stored on pegs on the unit base plate.

The impulse swirl meter uses a swinging honeycomb type matrix which is restrained from rotation by a strain-gauged load cell to totally arrest the angular swirl component thereby measuring the resultant angular impulse as a torque. Earlier methods of measuring swirl such as swirl vane meters, were dependent on the velocity profile of the air stream, whereas the impulse type of meter overcomes this limitation by responding to the total angular momentum flux in the swirling air flow.
....
The unit is designed for blow or suction induced flow and can be assembled for operation in either the upward or downward mode, whichever is most convenient. The Aeroweb honeycomb matrix is suspended within a cylindrical, aluminum housing with the skirt of the matrix immersed in an annular oil reservoir in the base which serves both as an air seal and a viscous damper. A set of weights is provided with the instrument to facilitate static calibration of the strain gauge with an accuracy of 2%. The matrix is mounted on an axle in the frame and supported by precision ball bearings while the torque arm connected to the axle acts on a Wheatstone Bridge strain gauge transducer. Cussons Display Unit, used in conjunction with the swirl meter, is a mains operated instrument complete with power supplies, which converts the strain gauge measurement into a four element, LED digital readout.
Application:
In automotive and truck size engines for instance, a pressure drop of 254 mm water gauge is normally used. The illustration shows a typical test rig layout arranged for downward air flow, in which the clients manometer registers a constant pressure drop across the model which must always be high enough to ensure fully turbulent flow in order that the results can be applied to his own particular engine configuration.
A low range strain gauge transducer measures the positive or negative force caused by the torque reaction produced when swirling air is straightened by the honeycomb. This torque is normally calibrated over a small range for higher accuracy.
The display unit contains the signal conditioning electronics in a rack mounting module.
The front panel carries the 4 digit LED display, a main on/off switch and zero and span potentiometers. The rear panel connections include a 10V analog signal for connection to the data acquisition system.
The matrix is connected via a torque to a strain gauge transducer which is calibrated by suspending weights over pulleys either side of the torque arm.
The length of torque arm is such as to enable torque values up to 0.1Nm to be The unit shall be arranged for flow in an upward and downward direction and is supplied complete with adaptor plate having a pilot bore of diameter 50mm.
Swirl meter comprises a Honeycomb matrix mounted within cylindrical housing.
